Method of crystallizing phenylalanine. |
| 摘要 |
<p>A method of crystallizing phenylalanine in the form of alpha -crystals at a temperature below alpha -> beta transition temperature comprises: forming an aqueous solution of phenylalanine at a temperature above the alpha -> beta transition temperature, the aqueous solution of phenylalanine including: (1) a specified amount of NaCl, or (2) NH4Cl and a small amount of a surfactant; and cooling the solution below the alpha -> beta transition temperature. h</p> |
